IMPROVEMENT IN BRUSH-MAKING MACHINES.

Specification forming part of LettersPatent No. 156,534, dated November3, 1874; application filed July 13, 1874.

To all whom it may concern: 7

Be it known thatwe, HENRY A. UARRING- 'roN,'of New Haven, and BARNARDLAVERY,

of East Haven, in the county of New Haven and State of Connecticut, haveinvented a new Improvement in Machine for Making Brushes; and we dohereby declare the following, when taken in connection with theaccompanying drawings and the letters of reference marked thereon, to"be a full, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and rep resent, in

Figure 1, a side view; Fig. 2, a front view;

Fig. 3, a longitudinal central section; Fig. 4, a sectional plan view online :1? m,- Figs. 5, 6, 7, detached views to illustrate the operation.This invention relates to an improvement in devices for automaticallyfeeding the tufts to the setting apparatus in brush-making machines,designed with special reference to the class of machines patented by A.M. White, December 22, 1868, and subsequent patents, but applicable toother setting devices; and the invention consists in combinations ofmechanism, as hereinafter described, for determining and taking therequisite quantity of bristles from the mass, and delivering the same tothe setting apparatus.

A is the bed of the machine, above which, in suitable bearings B, thedriving-shaft B is arranged and made to revolve by the application ofpower thereto in any convenient manner. 0 is the head in which thesetting mechanism is arranged; but this is not shown, it not beingessential to this invention. D is the hopper to receive the bristles inmass, and consists in a box arranged longitudinally in the machine, thewidth of the box corresponding tothe length of the bristles. The innersurface, top and bottom, is provided with longitudinal ribs d, uponwhich the bristles lie, in order to prevent friction upon the wholesurface of the box. Within the hopper a follower, D is arranged totraverse the length of the box, and is made to press against the rear ofthe mass of bristles in the hopper by means of a weight, D or other.suitable device, which will move the follower and crowd the bristlesforward as portions are taken away. The forward end of the hopper isclosed, and is provided with vertical ribs d, corresponding to thelongitudinal ribs, so that the follower presses the mass of bristlesagainst the ribs on the front end. At the forward end there is anopening at the top, as seen in Fig. 6, through which the bristles areraised from the hopper. Above the mouth of the hopper a slide,E, isarranged, which has a vertical reciprocating movement imparted to it bya cam, E. This slide carries a pointed divider, e, which in its descentpasses down through the mass of bristles, separating a certain quantity,as seen in Fig. 3, the mass thus cut oif represented by stipple section.An arm, F, extends from the slide over the mass. Beneath, a compressor,G, is attached to a lever, G which is forced up against this separatesection by means of a spring, G thus forcing the mass up into a cavityin the arm F. So soon as the mass has risen to the height to force therequisite quantity into the arm F, a separator, L, is advanced by theaction of a cam, L through levers L which passes through the mass,separating from the upper portion of the divided mass the requisitequantity for a single tuft. This separator L is inclined upon its uppersurface, and it continues to pass beneath the arm F, holding the tuft,and causing it to rise with the slide E up to the position seen in Fig.5. As the separator L only enters the center of the mass, it isdesirable to separate the different fibers of the separated portion fromthe fibers below throughout their length. To do this there is attachedto the separator L, as seen in Fig. 6, a pair of auxiliary separators,a. These advance with the separator L until their points have passedthrough the mass.

They are then caused to throw out to the right 7 and left, as seen inFig. 6, by means of curved slots in the separators a working over studsstationary on the hopper, as seen in Fig. 6. These separate the tuftsentirely from the mass below. The requisite quantity for the tuft havingbeen thus separated from the mass and raised therefrom, it is necessaryto take the tuft and carry it forward to the setting device. To do thisa slide, N, is arranged above the hopper, to which a reciprocatingmovement is imparted by the cam N through levers N This slide carries apair of fingers, n, and near each side of this slide N is a bar, I, eachterminating in a finger, m, the fingers m lying in front of theseparated portion, as seen in Fig. 5. The fingers m rest while thefingers 1?. advance and grasp the tuft between the said fingers n and m,as seen in Fig. 7. The slide E then rises sufficiently'to clear thetuft, and the fingers, grasping the tuft, are then advanced to presentthe tuft to the set-' ting apparatus, as denoted in broken lines, Fig.7.

The bars P, which carry the fingers m, are caused to operate at theproper time in the following manner, as shown enlarged in Figs. 9 and10: Starting from the position seen-in Fig. 9, the slide N moves forwardto the position denoted by the broken lines. The bars P are preventedfrom moving during this time by a spring, 25, lying upon the slidesforward of a lug, i, on the said bars P; but when the slides N havereached the position denoted in Fig. 9, a projection, 'r, on the slide Nstrikes a ing, f, on the bars 1?. At this time the fingers n have beenbrought into the position relative to the fingers m, as seen in Fig. 7,and grasped the bristles for the tuft. From this point the projections7' cause the bars to move forward with the slide N, carrying thefingersand the tuft, which they embrace, to the extrenle forwardposition, as seen in broken lines, Fig. 7, and as seen in Fig. 10. Whenthe tuft has thus been carried forward it is taken by the settingapparatus, and the slide N is moved back. When the bars P have reachedtheir extreme forward position, as seen in Fig. 10, another spring, 8,falls in rear of a lug, u, on the bars P, as seen in Fig. 10. Thisprevents the fingers a from moving back with the slide until after thetuft has been carried down from the fingers. In returning, theprojections r on the slide N strike the lugs i on the bars P, as seen inbroken lines, Fig. 10, and from that point the bars? are forced backuntil both slides and their fingers come into the first position orplace of rest, as seen in Fig. 9, and also seen in Fig. 3. As the tuftsare necessarily set close together in the setting of each succeedingtuft, there is a liability of entangling the setting tuft withpreviously set tufts. To avoid this a yoke, R, is arranged in front ofthe fingers m n, on a slide, R this yoke being of sufficient width toallow the fingers with the tuft to pass over it, as seen in Fig. 2, andto be turned down through it. The slide It has a longitudinal movementimparted to it by a cam, R through levers R and this is moved forwardwith the fingers and tuft, as seen in broken lines, Fig. 7. This pressesback the previously-set tufts in all directions, as seen in Fig. 7, sothat as the tuft is carried down all liability of entanglement isavoided. The hopper Dis of greater depth than the body required for asingle tuft. The divided portion is carried up, as before described, by

compressor G, by the pressure of the spring G but after each operationor removal of the bristles for a tuft the compressor G is returned tothe bottom of the hopper by means of a cam, G ,'through a rod, G workingin a slot, G in the end of the lever G This will always bring thecompressor down to the same point; but the slot will allow variation inthe rise, so that the same movement of the compressor G will answer fordifferent-sized tufts. The action of the spring Gr compresses thebristles for the tuft between it and the arm F, and that againcompressed in a transverse direction by the fingers n m, so that thebristles are brought into a close, compact form before presentation tothe setting apparatus. As soon as the compressor has dropped to itslowest position, and the divider e raised, the mass of bristles in thehopper is pressed forward by the follower D to supply the place of thelast-taken tuft.

The quantity of bristles taken for a tuft may be varied or adjusted bymeans of the arm 'F, which is constructed as seen in Figs. 11 and 12,enlarged. A slide, T, is attached to the arm, and an adjusting-screw, W,arranged to move the slide to or from the divider e. The space betweenthe slide T and the divider 0 will always be filled by the bristlespressed up by the compressor G; hence,

as that space is greater or 1ess,the tuft will be accordingly greater orless. This adjustment may, however, be accomplished by raising the armF.

It is necessary that the divider 0 pass completely through the mass, andmeet the compressor Gr below, as seen in Fig.3. In order to prevent thedivider from forcing the bristles down through the bottom, beside thecompressor, a slide or false bottom, V, is arranged, pressed forward bya spring, V, as seen in Fig. 3, and yielding as the divider strikes itsend, and falling back as the divider descends, and returning as thedivider ascends to close up against the compressor G, and thus preventany opening in the bottom through which the bristles may be forced, andthereby prevent the successful working of the feeding device.

By the use of the Word bristles, we wish to be understood as embracingall materials used for making brushes.
